What Is a Geothermal Loop System?

Geothermal systems use the constant temperature of the earth to heat and cool buildings. At the heart of this system is the geothermal loop field—a network of pipes buried underground that circulates fluid to exchange heat with the earth.


These closed-loop systems are

  • Highly Energy Efficient
  • Environmentally Friendly
  • Long-Lasting and Low-Maintenance
  • Ideal for Both Homes and Commercial Buildings


Nash Drilling LLC installs horizontal and vertical loop fields, depending on your site, soil conditions, and heating/cooling demands.
